RESUMO
BACKGROUND: This study aimed to investigate the effects of the Kidney-Tonifying and Blood-Activating Formula on combating the downregulation of integrin ß3 and integrin ß5 in mouse placental tissue induced by phospholipid antibodies. OBJECTIVE: This study aimed to investigate the effects of kidney-tonifying and blood-activating formulations on combating the downregulation of integrin ß3 and integrin ß5 in mouse placental tissue induced by phospholipid antibodies. METHODS: Mice in the phospholipid antibody group and phospholipid antibody + kidney-tonifying and blood-activating formula group underwent repeated implantation experiments, and the expression of integrin ß3 and integrin ß5 in placental tissue was observed. The effects of the kidney-tonifying and blood-activating formula on mouse placental tissue were evaluated through biochemical index tests, histopathological observations, and immunohistochemical staining. RESULTS: After intervention with the kidney-tonifying and blood-activating formula, the expression of integrin ß3 and integrin ß5 in placental tissue was notably upregulated, and placental structure was restored. Kidney-Tonifying and Blood-Activating Formula significantly improved abnormal biochemical indices and exerted a remarkable protective effect on placental tissue pathology. CONCLUSION: The kidney-tonifying and blood-activating formula effectively counteracted the downregulation of integrin ß3 and integrin ß5 in mouse placental tissue induced by phospholipid antibodies and alleviated placental tissue pathology through structural improvement and protection. Therefore, kidney-tonifying and blood-activating formulas may serve as potential therapeutic agents for recurrent implantation failure, offering new insights and approaches for clinical treatment.
